Checks the spelling of an email address to detect typos and spelling errors. If the email address has a valid syntax its mail server is determined and checked for existence. The mail server itself will be compared with a list of disposable providers to detect addresses with a short lifetime. Additionally the mail server will be checked if an email for the given mailbox can be received.
The API uses the POST request method to send data in the HTTP message body to avoid data being stored in the cache of the web server. A request is valid if all parameters are provided as described below (data type, minimum and maximum length). Please note that all data must be UTF-8 and URL encoded.
| Parameter | Mandatory | Data Type | Min. | Max. | Description |
|---|---|---|---|---|---|
| license | required | string | 29 | 29 | Your license key used for authentication - keep this key secret! |
| guid | required | string | 30 | 40 | Your GUID used for authentication - keep this key secret! |
| requestproof | optional | string | 0 | 1 | set to 1 if you need a unique request identifier as proof for your API request e.g. for VAT checks; default is 0 |
| returnavailablecredits | optional | string | 0 | 1 | set to 1 to get the number of data.mill credits available in your data.mill account; default is 0; a return value of -1 means that you have unlimited credits |
| responseformat | optional | string | 3 | 4 | format of returned data; possible values are xml or json (default) |
| required | string | 1 | 320 | The email address to be checked |
The API returns all data in valid JSON. A few programming languages include native support for JSON. For those that don't, you can find a suitable library at http://www.json.org. Valid requests always returns all response keys listed below. Depending on the request parameters some response keys may be empty.
| Name | Data Type | Description |
|---|---|---|
| valid | string | Flag if the spelling is valid, the mail server exists and would receive a mail for the given mailbox. The response may be unknown if the mailbox has an indeterminate status like greylisted or catch-all.
|
| description | string | Empty if the email address is valid, otherwise a description why the email address is invalid or unknown.
|
| status_code | string | Unique status code for each possible validation state
|
If the request fails the API returns a HTTP status code according to the reason. A reason may be a missing mandatory request parameter, invalid parameter credentials (minimum/maximum length) or invalid API keys. The response body is a valid JSON containing detail information about the reason (except for status code 500).
| HTTP Status Code | Reason |
|---|---|
| 401 | Unauthorized The license key and/or GUID key is missing, invalid or inactive. |
| 402 | Payment Required Your /data.mill credit quota is exceeded. You need to get more credits. |
| 403 | Forbidden You need to accept all required agreements of this function to be able to use it. |
| 404 | Not Found The request path in combination with the request method does not exist. |
| 405 | Method Not Allowed The request method is not allowed for the requested path. |
| 412 | Precondition Failed At least one of the given request parameter has invalid credentials (e.g. data type, length). |
| 428 | Precondition Required At least one of the mandatory request parameter is missing or has an empty value. |
| 500 | Internal Server Error An unexpected condition terminated the request. |
| 503 | Service Unavailable The service is currently in maintenance mode and will be alive later. |
The batch mode allows the execution of thousands of records (limited to 5,000) combined in a single request. This API endpoint as described above uses the single mode execution of records. To use the batch mode you need to combine all request parameters above (excluding license and guid) as array, where each array element represents a single record. This array is converted to a valid JSON string and set as value of the new request parameter called batch. The response of the batch mode is a valid JSON which contains the result for each record set in the request. The response keys of each result element are the same as for the single request mode described above.
In order to enable the payment of different currencies, we have introduced a system based on credit balance as payment for the individual functions. The currency of the account is called /data.mill credits. To use the functions, the account must be charged in advance. If the credit price of a function is higher than the current balance, the function can not be executed. The credits will be deducted from your balance after executing the function. Your credits have no expiration date.
We provide some code snippets for multiple programming languages to easily implement this function in your own application. The code snippets below uses the single request mode. If you want to use the batch mode instead of the single mode you need to modify the snippet. Feel free to copy the code snippets for your preferred programming language.
